SNOW AND ICE SCRAAPEIM Specicaton of Letters Patient.

Application med April 27, i908. `sei-iai No. 429,435.

To all whom it may concern.' i

Be it known that I, -WILLIAM Cnoss, residing at Vinnipeg, Province of Manitoba, 'Dominion of Canada, have invented certain new and useful Improvements in Snow and Ice Scrapers, of which the following is a specification.

My invention relates `to certain new and useful .improvements in snow and ice scrapers for use on railroads and the like, and in its generic nature the invention embodies a scraper located behind the leading engine truck wheels of a locomotive to coperate with the pilot plow in clearing the tracks of ice and other similar obstructions.

In its generic nature the invention em bodies a scraper mounted on the truck frame projecting down into engagement with the track rail, andmeans for automatically` projecting the scraper plate into engagement with the track rail at times and means for normally holding the scraper out of engagement vwith the track rails when not in use.

My invention also seeks to provide a device of this character which will not be in the way of the tracksignals particularly those of the explosive type which arefastened to the rail and will therefore not interfere with safety signals being placed. on the track and thus will not render the system unsafe.

In its more subordinate nature the invention embodies those novel details ofconstruction, combination and arrangement of parts, all of which will be first described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which :M-`

Figure 1, is a side elevation of a track embodying my invention. Fig. 2, is a plan view thereof. Fig. 3. is a cross section on the line 3'-3 of Fig. 1. Fig. 4, is a detail perspective view of one of the brackets which are secured to the evener bars or other portion of the truck, and in which the operating shaft ismounted. Fig. 5, is a perspective view of one of the lever members that are carried by the operating shaft and to which the Scrapers are pivoted, Fig. 6, is a perspective view of one of the Scrapers, Fig. 7, is a detail diagrammatic side elevation show ing the manner of operation of my invention should the scraper meet an obstruction, and showing the manner in which it is released. Fig. 8, is a detail section showing the position of the scraper when in its normal position out of engagement with the rail.

reference indicate like parts in all of the fig` ures, l represents the front truck of a locomotive having the usual equalizer bars, which' truck is provided with the usual wheels 2 to run on the tracks 3, the construction of the `truck may be of any approved type, as the same per se forms no part of my present invention.

Bolted to the equalizer bars of the truck, or to any other suitable portion of the truck frame, and at each side thereof, is a bracket 4 which is provided with a bearing portion 4X to receive the rock shaft 5 which passes from sideto side of the truck and through supplemental bearing members 20 securedV to the inside of the equalizer bars of the truck. Secured to the projecting ends of the shaft 5 at each side of the truck is a lever member 6 which has a hub portion 6b keyed to the shaft 5 and also held in place by asuit t able 'nut 5a, and the lever member 6 is also provided with a strengthening web 6a and another bearing portion `in `which. the stub shaft or bolts 8b are mounted, the bolts 8b also passing through the ears 8a ofthe.

scraper support 8 to which the scraper 9 is secured in any approved manner. The scraper 9 is formed with a projection 9a which is adapted to enter the groove of the rail, when a grooved rail is in use, or to project alongside of the rail when a T-rail is used. The scraper 9 is also provided with acurved upper end 9b to throw oif the snow and ice as it is scraped up on the rail.

In order to hold the scraper 9 at the proper distance above the rail, as shown in Fig. 1, I provide a hanger 7 which is pivoted at 7a to the` web 6a of the lever member 6, and which projects through an aperture 4a in the upper web of the bracket L and is secured by a check bolt 7 b, as shown, the bolt 7 having a free upward movement through the aperture L1, but the check nut 7e serves to limit the downward movement thereof which downward movement may be adjusted by adjusting the check nut. 1 In order to; limit the backward swing of the Scrapers 9 and their supports 8 on the fulcrum 8", I provide a rod 10 which is linked to the scraper 9, by an eye bolt 9c, as indicated in Fig. 1 of the drawings, and the rod 10 passes through the enlarged aperture 10z of a bracket 10x that is bolted at 10y t the frame of the truck. j j

The rod 10 is secured to an S-hook 12 by links 11, the S-hook being in turn secured to an eye-bolt 13 that passes through a portion of the frame of the truck, the S-hook 12 is made of smaller iron than the stay rod 10, so that in case the scraper strikes any hard obstruction it will swing back and the S-hook will open to disconnect the stay rod 10 from the bolt 13, it being understood that the bracket 10X supports the stay rod and prevents it falling down and engaging the road bed or track.

14 designates a lever clamped to the shaft 5 to which the piston rod 15 from the air piston cylinder is pivotally connected at-la. The piston rod 15 also connects with the piston 1G that operates in the air cylinder 16, a coil spring 16b being provided in the cylinder to normally move the rod 15 in the direction of the arrow in Fig. 1, so as to hold the scraper 9 up in the position shown in Fig. 8 of the drawings, out of its operative position with respect to the track, so that in case track signals are used on the road'the scraper will not displace them. The cylinder 1G is connected through a port 17 with the air supply system of the locomotive and is controlled by any suitable valve in the engineers cab, so that when the engineer opens his valve and allows the cylinder 16 to be filled with compressed air from the tank the piston will be forced into a direction opposite to the arrow in Fig. 1 androtate the shaft 5 to move the Scrapers 9 into their operative relation with respect to the rails of the track, see Fig. 1. Stud bolts 21 are preferably secured into the back boxes againstthe equalizers, as shown, to prevent the equalizers moving backwardly when my invention is applied thereto. It should be stated that the Scrapers 9 are preferably arranged at an angle to the tread face of the rail so as to throw the debris to one side of the track and preventl it accumulating between the rails.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains, and I desire to say that numerous changes in the details of construction may be readily made without departing from the spirit of the invention or the scope of the appended claims.
